Prospects for Large Relativity Violations in Matter-Gravity Couplings [PDF]

, 2008
Deviations from relativity are tightly constrained by numerous experiments. A class of unmeasured and potentially large violations is presented that can be tested in the laboratory only via weak gravity couplings. Specialized highly sensitive experiments

Relocation risky for bumblebee colonies [PDF]

Science, 2015
We do not dispute the results of the Report “Climate change impacts on bumblebees converge across continents” (10 July, p. [177][1]), in which J. T. Kerr et al. show that shrinking bumblebee ranges track temperature changes in unexpected and alarming ways at a continental scale ...

An overview of agricultural neonicotinoid regulation in the EU, Canada, and the United States

Pest Management Science, EarlyView.
Grounded in broad environmental coalition and place‐based research, the European Union, Ontario and Québec in Canada, and several US states placed restrictions on agriculturally‐applied neonicotinoids. The exact regulations and how they were implemented are explored.

Cognitive dimensions of predator responses to imperfect mimicry? [PDF]

, 2007
Many palatable insects, for example hoverflies, deter predators by mimicking well-defended insects such as wasps. However, for human observers, these flies often seem to be little better than caricatures of wasps – their visual appearance and ...

Gradual pollen release in a buzz‐pollinated plant: Investigating pollen presentation theory under bee visitation

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The rate at which flowers dispense pollen across successive pollinator visits is a key functional trait influencing male reproductive success. Pollen presentation theory (PPT) predicts that when pollinators are abundant and actively groom their bodies to collect pollen,

Infestation levels of Aphomia sociella in bumblebees increase with proximity to apiaries and result in lower reproductive output and weaker immune response

Frontiers in Bee Science
IntroductionBumblebees are essential pollinators in temperate regions of the northern hemisphere. Niche overlap and competition with honeybees may impose significant stress on bumblebees by reducing nutrient acquisition and increasing the risk of ...

Long‐range pollen transport across the North Sea: Insights from migratory hoverflies landing on a remote oil rig

Journal of Animal Ecology, EarlyView.
This study identifies pollen from over 100 plant species—including wildflowers, food and crops—carried by hoverflies alighting onto an oilrig 200 km off the coast during seasonal migrations. Analysis of their movements indicates a huge potential to enhance long distance gene flow between plants and increase pollination services.

Metabolomics-based biomarker discovery for bee health monitoring : a proof of concept study concerning nutritional stress in Bombus terrestris [PDF]

, 2019
Bee pollinators are exposed to multiple natural and anthropogenic stressors. Understanding the effects of a single stressor in the complex environmental context of antagonistic/synergistic interactions is critical to pollinator monitoring and may serve ...
